Excellent! By Loren on 4/22/13
Loren would recommend this product to a friendHooked it up out of the box, was getting a reading instantly. Great for letting you know when you need to replace your filters, so in a sense saves you money. And keeps your aquarium clean and in tip top shape. I will not go with out one anymore. -
